A simple font selector would be nice. I have some seriously impaired vision w/o correction and monospaced fonts really help when I have to look at a screen that way.
That and ability to zoom in/out or increase/decrease font size.
Note that Bike does support changing font size already.
I'm getting a lot of request for also adding changing the underlying font. Will likely add that sooner then later now since lots of people seem to need.
Is there any way to change the font? As a developer, non-monospace fonts feel foreign for composing text.
